Turbulent Heat Transfer

Heat transfer problems in turbulent flows are mainly described by empirical relationships Nu = Nu(Re, Pr). The progress of modeling the turbulent heat transfer is quite poor. For the turbulent momentum transfer on the other hand we have a lot of semiempirical modeling assumptions which lead to good results for engineering purposes. After an introduction into the closure assumptions for the turbulent momentum transfer the turbulent heat transfer, in particular the turbulent Prandtl number are discussed. Finally a model to predict the turbulent Prandtl number is proposed. It can be used to calculate heat transfer correlations Nu(Re, Pr).
